Jump distance per step in bounding exercises from the standing position increases with increasing number of steps. We examined the hypothesis that the joint kinetic variables of the stance leg would also increase accordingly. Eleven male athletes (sprinters and jumpers) performed bounding exercise, starting from the double-leg standing posture, and covered the longest distance possible by performing a series of seven forward alternating single-leg jumps. Kinematic and kinetic data were calculated using the data by a motion capture system and force platforms...

The carotid glomus is an anatomical structure located in the bifurcation of the common carotid artery and consisting of chemo and baroreceptors. It is an important reflexogenic zone participating in provision of constancy of arterial pressure. Performing eversion carotid endarterectomy is accompanied by damage of the structures of the carotid glomus, which is followed by persistent arterial hypertension in the early postoperative period. This complication remains one of the unsolved tasks in surgery of carotid arteries...

Knowledge of anatomical variations of the division of the popliteal artery and specific lesions of the arterial segment involved is necessary for the surgeon, traumatologist-orthopaedist, vascular surgeon. The article contains a review of recent literature data on the prevalence of different variants of branching patterns of the arteries of the crus, also providing a detailed discussion of embryological development of the arterial system of the lower extremities, in many ways explaining the appearance of rare pathologies of the popliteal artery, such as for example popliteal artery entrapment syndrome...

A femoral approach is the main access in stenting of carotid arteries, mainly due to rapid training in how to perform the procedure and a possibility of using large-diameter catheters. However, this approach is not always feasible in atherosclerosis, tortuosity of lower-limb arteries and in certain anatomical peculiarities of the aortic arch. Using a transradial approach is based on the desire to diminish the incidence rate of haemorrhagic complications in the zone of the puncture and to avoid the necessity of a long-term bed rest...

In this review, we discuss first the anatomical and lesion studies that allowed the localization of fundamental functions in the cerebral cortex of primates including humans. Subsequently, we argue that the years from the end of the Second World War until the end of the last century represented the "golden age" of system neuroscience. In this period, the mechanisms-not only the localization-underlying sensory, and in particular visual functions were described, followed by those underlying cognitive functions and housed in temporal, parietal, and premotor areas...

PURPOSE: To determine the extent to which (1) optic nerve tissue is displaced following mild acute elevation of intraocular pressure, and (2) clinically accessible measures at the anterior eye can be used as a surrogate for such displacements. METHODS: We imaged the optic disc of 21 healthy subjects before and after intraocular pressure (IOP) elevation of ~10 mmHg delivered by ophthalmodynamometry. Steady-state tissue displacement during IOP elevation was assessed axially from OCT data, and laterally from SLO data...

BACKGROUND: Enteral feeding via feeding tube (FT) provides essential nutrition support to critically ill patients or those who cannot intake adequate nutrition via the oral route. Unfortunately, 1%-2% of FTs placed blindly at bedside enter the airway undetected (as confirmed by x-ray), where they could result in adverse events. Misplaced FTs can cause complications including pneumothorax, vocal cord injury, bronchopleural fistula, pneumonia, and death. X-ray is typically performed to confirm FT placement before feeding, but may delay nutrition intake, may not universally identify misplacement, and adds cost and radiation exposure...

Subcutaneous fat necrosis of the newborn is a rare benign panniculitis found in term and post-term neonates. Diagnosis is based on clinical characteristics and specific alterations in the adipocytes, detected by anatomical pathology. Subcutaneous fat necrosis of the newborn can occur in uncomplicated pregnancy and childbirth. However, perinatal complications such as asphyxia, hypothermia, seizures, preeclampsia, meconium aspiration, and even whole-body cooling used in newborns with perinatal hypoxia/anoxia may be associated with this entity...

An 83-year-old woman with a Kommerell diverticulum was treated by anatomical endovascular repair with a deep site in-situ fenestration instead of complex debranching techniques. The main component of the thoracic stent-graft was deployed just distal to the third cervical branch to completely exclude the Kommerell diverticulum. A deep site in-situ fenestration was made on the main component using a radiofrequency needle through the left subclavian artery, and a stent-graft was deployed to bridge the main component to the left subclavian artery...

The cerebral venous system is an unusual site of thrombosis, with a particularly high incidence in young adults. This incidence has increased in past decades because of the improvement of neuroradiological techniques. Risk factors for cerebral venous sinus thrombosis overlap with those of other venous thromboembolism sites, however, some are specific for this particular anatomical district. Prognosis is favorable in most cases if diagnosis is made rapidly and treatment is promptly initiated, even if acute complications or chronic invalidity still occur in a quarter of patients...

Multiparametric magnetic resonance imaging (mpMRI), which combines traditional anatomic and newer quantitative MRI methods, has been shown to result in improved voxel-wise classification of prostate cancer as compared with any single MRI parameter. While these results are promising, substantial heterogeneity in the mpMRI parameter values and voxel-wise prostate cancer risk has been observed both between and within regions of the prostate. This suggests that classification of prostate cancer can potentially be improved by incorporating structural information into the classifier...

Endomyocardial biopsy (EMB) is considered to be the diagnostic gold-standard in detection of myocardial-inflammation. EMB is usually conducted under fluoroscopy without any specific target information. Specific target-information provided by cardiovascular magnetic resonance (CMR) may improve specificity of EMB. The aim was to investigate feasibility and safety of CMR-guided and targeted EMB in a preclinical-model using passively-tracked devices. Procedures were performed on a MRI-System equipped with an Interventional Software-Platform for real-time imaging...

Bariatric surgery has proven to be the most effective weight loss strategy in severe obesity. Imaging in the immediate postoperative period of bariatric surgery is not done routinely. However, it is helpful in the assessment of early and late complications, which are estimated to be present in < 1% of patients. In some cases, the imaging interpretation of anatomical outcomes and complications related to these procedures represents a challenge for surgeons and radiologists. The aim of this review is to describe the imagenologic findings after bariatric surgery and focuses on the findings of the most frequent procedures performed in Colombia such as laparoscopic sleeve gastrectomy, laparoscopic Roux-en-Y gastric bypass, and laparoscopic adjustable gastric banding...
